Farmers participating in the public benefit direct payment system are required to comply with standard fertilizer use guidelines. However, the optimal fertilizer rates for water dropwort (Oenanthe javanica DC) cultivation have not yet been established, resulting in inefficient fertilizer use and inconsistent yields. To determine appropriate fertilizer standards, a two-year field experiment was conducted to evaluate the growth response and fertilizer use efficiency of water dropwort under five fertilization levels (0, 0.5, 1.0, 1.5, and 2.0 times the average farm application rate of N–P2O5–K2O = 320–140–150 kg ha-1). Plant height increased when nitrogen was applied at or above the standard rate and when phosphorus and potassium were applied at double the standard rate, whereas SPAD values showed no significant differences among treatments. The highest yields were obtained with nitrogen at 1.0×, phosphorus at 1.5×, and potassium at 1.5×. Fertilizer partial factor productivity (FPFP) was greatest at 0.5× for all nutrients, showing no significant variation between years, while fertilizer agronomic efficiency (FAE) did not differ significantly among phosphorus treatments. Fertilizer recovery (FR) was highest at 0.5× for nitrogen and phosphorus and at 1.5× for potassium. Based on two years of yield data, the optimal fertilizer rates for maximum yield were estimated to be 320 kg N ha-1, 140 kg P2O5 ha-1, and 225 kg K2O ha-1. These results provide a scientific basis for establishing customized fertilization guidelines that consider soil nutrient variability and aim to enhance fertilizer efficiency in water dropwort cultivation.
